Objective To discuss the diagnostic value of CT in the hip joint dislocation.Methods We analyzed and compared 17 cases of the hip dislocation examined by X-ray and CT.Results X-ray plain film displayed hip joint dislocation in 15 cases,fractures in 10 cases,soft tissue swelling in 9 cases,widened hip joint space in 6 cases and bone fragment in 3 cases after restoration.CT showed hip joint dislocation and fractures in 17 cases,soft tissue swelling in 15 cases,widened hip joint space in 11 cases and bone fragment in 10 cases after restoration.Conclusion For the direction and the degree of hip joint dislocation,acetabulum fracture,bone fragment in articular space and soft tissue swelling,CT has distinct advantage.We find that CT may be one of a routine method in hip joint dislocation,especially after restoration.

Objective To investigate the effect of ligustrazine on autophagy-related proteins Beclin 1,LC3 and P62 after spinal cord ischemia-reperfusion injury.Methods A total of 48 SD rats were randomly divided into sham operation group,model group,ligustrazine group and 3-MA group.The rats were intraperitoneally injected with ligustrazine injection 0.16 mg/kg in the Ligustrazine group,the rats were intraperitoneally injected with 3-methyladenine injection 0.015 mg/kg in the inhibitor group,and the rats were intraperitoneally injected with normal saline of equal volume in the sham operation group and model group.Spinal cord ischemia-reperfusion model was established in all groups except sham-operated group after administration.After molding behavioral scores were scored after 3 and 6 hours of ischemia,and the expression of Beclin 1,LC3 and P62 was detected by immunohis-tochemistry.Results After 3 and 6 hours,compared with the model group,the behavioral score (3 h:2.33 ± 0.58 vs.0.67 ± 0.58,6 h:3.33 ± 0.58 vs.1.33 ± 0.58) of the rats in ligustrazine group significantly increased (P＜0.05).Compared with the model group,the expression of Beclinl (3 h:348.00×104± 0.27×104 vs.659.00×104± 0.11×104;6 h:38.00×104± 0.19×104 vs.557.00×104± 0.26×104),LC3 (3 h:357.00×104± 0.48×104 vs.686.00×104± 0.33×104'6 h:334.00×104± 0.51×104 vs.673.00×104 ± 0.22×104),P62 (3 h:357.00×104 ± 0.48×104 vs.830.00×104 ± 0.48×104;6 h:315.00×104 ± 0.12× 104 vs.591.00× 104± 0.36× 104) in ligustrazine group were significantly decreased (P＜0.05).Conclusions The ligustrazine may regulate autophagy in two directions and protect nerve cells.
